Abstract
The pressure plate has at least one friction surface region which can be pressed against a friction facing arrangement of a clutch disk or the like, wherein the pressure plate is formed at least partially from a first material, and wherein a second material having thermal contact with the first material is provided in the pressure plate at least in some areas. In order to be able to compensate for negative umbrella deformation of the pressure plate caused by friction heat during operation of the clutch, the second material has a different thermal expansion, particularly a greater thermal expansion, than the first material.
